Question 1

What is order fulfillment software?

Accepted Answer

Order fulfillment software is the operating layer that moves an order from your storefront to the carrier. It pulls orders in, organizes pick and pack, generates carrier labels, sends tracking updates, and handles returns. It's broader than shipping software, which usually focuses on label printing and rate comparison alone. Postsale handles all of these jobs for ecommerce brands that ship through USPS, UPS, and FedEx, on a single subscription with no per-label software fees.

Question 2

How does Postsale handle the full fulfillment workflow?

Accepted Answer

Connect your storefronts and your carrier accounts in your Postsale dashboard. New orders import automatically into one grid. From there, your team picks orders in batches, prints packing slips, generates labels across USPS, UPS, and FedEx, and pushes tracking back to the storefront. Branded tracking emails go out as soon as a label prints. Returns are generated from the same dashboard. Each step closes the loop with the store, so order status stays in sync without anyone re-entering data.

Question 3

What's the difference between shipping software and order fulfillment software?

Accepted Answer

Shipping software is usually scoped to label printing, rate comparison, and carrier connections. Order fulfillment software covers the full path: order import, pick and pack workflow, label printing, tracking communications, and returns. Postsale is positioned as fulfillment software, not just a label printer. You can use it for label-only workflows on the smaller plans, or for the full import-to-returns flow on any plan, since the operational features are not gated by tier.

Question 4

Does Postsale support batch picking and packing?

Accepted Answer

Yes. Select multiple orders in the orders grid and Postsale generates the batch together: pick lists for the warehouse, packing slips printed in order, and labels for every order in the same pass instead of clicking through them one at a time. Output to a 4x6 thermal printer or save as PDF for a laser printer. Bulk status updates push back to the storefront when the batch ships, so customer-facing order status stays accurate without manual re-entry.

Question 5

Can Postsale auto-route orders by carrier or speed?

Accepted Answer

Yes. Default automation rules ship on every plan and cover common patterns like cheapest-rate selection and automatic USPS cubic pricing when it saves money. Custom automation rules are available on Expand and above. Rules are context-aware: a single rule can consider order value, destination zone, package weight and dimensions, carrier availability, and delivery speed at once, so a faster service for high-value orders and an economy service for lightweight ones can run from the same ruleset.

Question 6

What integrations does Postsale support for order import?

Accepted Answer

Postsale auto-imports orders from WooCommerce, BigCommerce, Square, Miva, and eBay. CSV import is available on every plan for marketplaces and bulk loads. Webhook order import (JSON via API) is available on the Soar plan for teams that need programmatic intake or want to feed orders from a custom system. Tracking numbers and fulfillment status push back to each connected storefront automatically once labels are generated.

Question 7

Does Postsale send webhook notifications for shipping events?

Accepted Answer

Yes, on Soar and above. Postsale's webhook subscriptions push events to your own URL the moment they happen: orders imported, labels created or voided, tracking status changes, order status changes, and order notes added or updated. Every request is signed with HMAC-SHA256 using a per-subscription signing secret so your system can verify the payload came from Postsale. Use it to keep an ERP, warehouse system, 3PL, or custom tooling in sync without polling.

Question 8

How does Postsale handle returns?

Accepted Answer

Returns management is included on every plan. Generate a return label from the original order in the same dashboard you use to ship outbound. Postsale uses pay-on-use return labels, which means you only pay carrier postage when the label is actually scanned into the carrier network. Unclaimed return labels never hit your bill. Return tracking sits next to the outbound shipment so support and ops can see the full lifecycle of an order in one place.

Question 9

Can I send branded tracking and packing slips?

Accepted Answer

Yes. Branded tracking emails, invoices, and packing slips are included on every plan. Default templates carry your logo and colors out of the box. Custom template editing is available on Expand and above for teams that want full control over layout and copy. Custom From email addresses are available on Thrive and above, so tracking emails arrive from your domain instead of a Postsale address. Customers see your brand at every step from confirmation to delivery.

Question 10

What does USPS Connect eCommerce mean for fulfillment cost?

Accepted Answer

USPS Connect eCommerce is the USPS commercial pricing program Postsale uses for domestic USPS labels. You connect your own USPS Business account and Postsale applies the discounted commercial rates automatically, with no volume minimums to qualify. For high-volume operators, the savings on Priority Mail, Priority Mail Express, and Ground Advantage compound across thousands of shipments per month. Discounted USPS rates are available on every plan, including Launch.

Question 11

Is there a free trial? What's included?

Accepted Answer

The free trial is 14 days with full access to the fulfillment workflow: order import, batch pick and pack, multi-carrier label printing, branded tracking emails, returns, and Discounted USPS rates through USPS Connect eCommerce. Cancel anytime from your account settings with no annual contracts and no cancellation fees. If you cancel during the trial you are not charged. Human support is available from day one, not gated behind a paid plan.
